Fusion of Disturbed Soil Feature for Down-Looking Ground-Penetrating Radar Mine Detection

摘要

For vehicle-mounted down-looking ground penetrating radar (DLGPR) systems, the largest response is typically due to the radar reflecting off the ground. Most DLGPR algorithms remove the ground bounce response as a first preprocessing step. The remaining subsurface response is then used to detect buried mines. It was observed that the ground bounce response over recently buried mines differs from the surrounding undisturbed soil. This suggests an approach in which the ground bounce response could be used to enhance detection performance. In this paper, we describe a technique for fusing the GPR ground bounce response with the GPS subsurface response to enhance mine detection performance. The technique is applied to data collected by a wide bandwidth impulse radar over buried mines in various soil conditions.
